This zone runs absolutely horribly on my computer, and thats quite a task. I tend to play with stuff like maximum grass at full distance. Simply put, I get better framerate in morrowind's propylon chambers than I do in Beldaburo Anga, and I have no clue why!

Edit: Also, this place seems to have a strange number of completely pointless rooms behind pointless doors. What the heck is up with Beldaburo? o.O;

Running any mods? That section of the dungeon really isn't that big..... No idea where the pointless rooms came from.
